PERFORATING-MACHINE FOR LEAVES 0R SHEETS.

To all whom it may concern! Be it known that I, CYRUs E. MOREIIOUSE, a citizen of. the United States, residing at Milwaukee, Wisconsin, have invented c'ertain new and useful Improvements in Perfo-ratinghfachines for Leaves or Sheets, of which the following is a specification.

This invention relates to an improved perforating and slotting machine for leaves or sheets.

The objects of the invention are: First, to provide an improved perforating and slotting machine of etlicientand superior design. Second, to provide in such a structure an improved slotting and perforating means. Third, to provide an improved adjusting means for spacing a gage or plurality of such devices. Fourth,to provide an improved method of perforating and slotting sheets for loose leaf binders.

Further objects, and objects pertaining to details of operation and economies of construction will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the mechanism described in the followinw specification.

The invention is clearly. defined and pointed out in the claims.

Patented Dec.2,1913. Serial No. 647,148.

III, certain portions being shownin full .lines.

Fig. IX is a detail sectional view on line 99 of Fig. VIII, showing details of the paper clamp. Fig. X is a detail view' of a portion of a loose sheet showing the style of perforation and slot therein.

In the drawing, similar numerals of reference refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Considering the numbered parts of the drawing, the frame is made of end sections or castings 1+1, which are coupled together by four. horizontal transverse round bars 2, which are-clamped thereto by suitable nuts 3 on the. ends thereof. Carried on these transverseround bars are a series of adjustable-frames 4, each carrying a paper perforatin and slotting device, the same being adjusta is to locatethe slots in the right place. Bosses '6 are provided at the center of each-frame 4., which are engaged by the screws 5, each of which is controlled by a hand wheel 7, one at each side'of the machine'fj, j

An adjustable paper table, with suitable paper clamp, is provided, with suitable means for; moving it up and down in front of thisframe .work, thefdetails of'which will be fullyldescribed hereafter.

The framesections 4 are secured in place after adjustment by means "of set screws 8+8, atea'chporner thereof.

A; buzz saw 9 for slitting the paper is on a suitable arbOrlO, carried in a bracket 11.

The bracket llj'is' adjustablysecuredon the upper edgielof theframe section 4, by a suitableg iide block 12 resting on a guideway 13. The block is clamped in place by a cap screw l l through a longitudinal slot 16 therein,1a series of holes lfibeing provided for the cap screw 14. Set screws 17 journal'ed in suitable bosses 18 engage screw threaded holes in the guide block 12 to facilitate accurate adjustment of the same. Suitable heads are provided for engagement spanner Wrench or otherwise for this purpose. 7

"Each saw arbor is driven by a pulley 19, which is driven by a belt QOfrom a suitable corresponding pulley driving wheel 21 through i ing the tension on each belt to insure proper. driving of the corresponding buzz saw.

On the front of each frame section 4 is a vertical tubular s indle 30, which is carried in a vertical tubu ar bearing 31. This tubular bearing 31 is apart of the vertical thin plate 32, whichis secured by suitable screws 34 or other means to the vertical plate 33, constituting a plart of the frame 4. The upper end of t e tubular shaft is enlarged to the size of the exterior of the tubulaf bearing 31', and is screw threaded at I 36. A rotary tubular cutter 35 is screw threaded onto and is carried'by the tubular spindle' The upper edge 37 of this cutter 35 ,is irregular, t e same bein brought to a circular edge on a circle .0 exactly the diameter of the exterior of the tubular bearing 31. This rotary cutter spindle ing shaft 58. The gears 57 arefjadjustable 30 is driven by the vertical revolving shaft 38, which has an enlarged head 39, wh1ch receives 'a head 40 on the lower end of the shaft 30 to which it is adjustably secured .biy the set screw 43. Vertical pins 41 are 1n head 40 and project through a plate 42 'into the headw39, whereby the parts are adjustably coupled together for driving the same and in such a way as to permit a slight adjustment toinsure the even running of the tubular shaft 30 in its tubular bearing 31.

The shaft 38 is adjustable in an eccentric bushing in the bearing 44, and extends into 45 a bearln 45 beneath. A thrust collar 48 is provi ed to contact with the thrust ball bearing 49. These parts are carried by the bracket 46, which is adjustable on an arm 47 on the front of the frame section 4. A suction. hose 50 is connected to the lower end of this boxing 45 to draw any chips that may be cut from the paper, down through the tubular cutter 35.

Each tubular cutter is driven by a bevel gear 51', which is driven from the corres onding gear 52 which meshes therewith.

ach gear 52 is mounted on a shaft 53 which is carried in suitable boxings 54, 55 at the sides of the frame 4. A bevel gear 56 is on the rear end of shaft 53 and meshes with the driving gear 57 on the transverse driv on shaft 58 by the set screws 59, so that they can be brought into mesh with the gears 56 after the frames 4 have been adjusted into the required position for the work intended.

The shaft 58 is provided with a pulley- 60, and has a driving belt 61-wliich is driven a from pulley 62 on the counter shaft 22. The

shaft 58 is carried in the journal boxes 63 at each side on the detachable arm brackets 64 secured to the back sides of the frame ends 1 at each end of the machine.

The adjustable paper table 65 is braced by brackets 66, which are provided with bosses 67, 68, which embrace the vertical guiding posts 69, which are seated in sockets 70, at

the bottom and bosses 71 on brackets 72 on 80 the end pieces of the frame. This arrangement permits the table to be moved up and down.

The table is moved up and down by the vertical screw 73, which fits into a thrust bearing 74 on the under side of the table 65 and engages in the threaded nut 74 at the bottom. Thisthreaded nut 74 rests in the sprocket 7 5 in the upper side of the cross frame bar 7 6. A set screw 77 preventsthe' rotation of the nut so that when the shaft 73 is rotated, it travels up and down within the same.

A beveled gear 82 is provided on the screw 73, and this is driven by a beveled gear 81 carried on thehorizontal shaft 79. Shaft 79 is journaled on the hanger on the underside of the table 65. The shaft 79 is driven liy the hand wheel 78, as clearly ap ears in Figs. I, II and VIII.

ounterba-lance wei hts 83, on the cables 84 disposed over gui e pulleys 85 are connected to bosses 86 on the table 65 for counterbalancing the same. Guide pulleys 88 into place on the table. A and screw 92,1

with a hand wheel 93 is inserted into the top cross bar 94 for forcingclam 90 to place. This cross bar- 94 is held in place on the vertical uide rods 91 by cap screws 95, 95. Adjusta le clamping guides 96, are

disposed above and below the stack of paper 101 for clamping the same in position. The

' ad'ustable guides 96 are secured to the front si es of the clamp 90, and the table 65 by suitable adjusting g- The guides 96 are jprovide'dfiwith; round apertures 99, iorq thapagsage ofthe circular cutter 35', andwith slotslwffor the passage of the circular 'or'buzzasaw. The sheets 101 bolts 97 slots 98' (see are thus" securely clamped in position to be perforated and slotted. They are, it will be observed, 'perforated at 102 with a round perforation, with a' slot at one side (see particularly Fig. X).

The suction fan 103 is connected to the couplings 45 by the hose 50 to draw air down through the tubular cutters and carry away the waste from the cutters.

I have thus described the various parts of my improved machine, and will now indicate their operation.

In the use of my device, a pile of sheets 101 is'placed upon the table 65, having been suitably jogged to place so that they are perfectly even. The clamp 90 is adjusted thereon and is screwed down to place, the guide portions 96 having been adjusted to the precise point required. The slotting and perforating sections are then adjusted exactly to correspond to the guide, and the table is elevated so that the sheets are entirely above the circular saws and the machine is set in motion. The table is then lowered by manipulating the hand wheel 78, when it will be observed that the buzz saw 9 first cuts a slot in the side of the sheet, as appears in Fig. VIII, substantially through to the back of the circular portion of the slot. The table is then carried'on downward so that the sheets pass into. contact with the rotary cutter 35 which cuts the round hole in the sheets of paper when it is revolved, and owing to the fact that the paper has been divided by the circular saw, the chips or pieces of paper are sucked downwardly and immediately away from the cutter so that there is a free surface presented for the cutting edge at all times. There is consequently no tendency to bind the cutter, and, owing to the fact that the cutter is supported well up toward the cutting edge by the plate 32, which enters the narrow portion of the slot formed by the saw, the hole is. cut perfectly straight through any mass of paper no matter how thick within the dimension and capacity of the machine. In this way a thick loose leaf catalogue can be cut at a single operation perfectly true and even. All of the perforations can be cut at the same time in exactly the same spaced relation, all of which is of very great advantage in avoiding the necessity for repeated adjustments.

A pile of leaves from seven to ten inches thick can be cut as even and as true as a half dozen sheet by an ordinary punch.

I have shown my invention embodied in an elaborate machine, with three of the cutters arranged in a gang. A pair might be made use of, and also, it will be very clear that a single cutting device might be made use of cutting one slot at a time, but where a large amount of work is to be done, this would result in a serious loss of time because all of the slots might as well be cutat the same operation.

I have shown the machine elaborately j vorked out for thepurpose in a preferred orm.
